pmap:tldr:b5cf5

The command "pmap --device ${pid}" is used to display a memory map of the specified process in Linux. Here's a breakdown of the command:

• "pmap" is the name of the command.
• "--device" is an option flag that instructs pmap to display the device or file backing each mapped memory region.
• "${pid}" is a placeholder for the process ID (PID) of the process you want to analyze.

By running this command with the appropriate PID, the pmap utility will show a detailed breakdown of the process's memory usage, including information about the device or file associated with each memory region. This can be helpful for troubleshooting memory-related issues or analyzing a process's memory usage patterns.
